SPECIFICATION forming part of Letters Patent No. 744,073, dated November17, 1903.

Application filed July 16, 1903. Serial 1%. 165,796. (No model.)

To o whom it may concern.-

Be it known that I, MERLE EDWIN HENDER- SON, a citizen of the UnitedStates, residing at Fort Valley, in the county of Houston and State ofGeorgia, haveinvented certain new and useful Improvements inHose-Couplings; and I do declare the following to be a full, clear, andexact description of the invention, such as will enable others skilledin the art to which it appertains to make and use the same, referencebeing had to the accompanying drawings, and to the letters of referencemarked thereon, which form a part of this specification.

This invention relates to new and useful improvements in hose-coupler;and it consists in the provision of simple and efficient means forquickly and securely coupling the ends of hose together, and morespecifically comprises two collars or bands which have hingedconnection, and one of said bands carrying a lever, while the other isprovided with a tongue designed to be engaged by a spring-actuated pawlcarried by the lever, whereby as the lever is thrown down over thetongue the two ends of the coupler are brought together by cam action ofparts of the coupler, thus producing a tight joint.

The invention consists, further, in other details of construction and inarrangements of parts, which will be hereinafter fully'descri bed andthen specifically defined in the appended claim. 7

My invention is illustrated in the accompanying drawings, in which-Figure 1 is a side elevation of my improved coupler, the lever beingshown in dotted lines in the position it assumes when not in a connectedrelation. Fig. 2 is a central longitudinal sectional View through thecoupler.

Reference now being had to the details of the drawings by letter, A andA designate two coupling-heads having flanges a, intermediate whichwashers B are adapted to be placed before the heads are coupledtogether.

D and E designate collars or bands,'one of which, D, is provided with atongue D, having a cam edge d and a shoulder 11', adapted to rest overthe flange of one of the couplingheads when the latter are heldtogether. Said cam edge has a notch F therein adapted to be engaged by apawl about to be described.

connection between the two collars.

Integral with the collar D at a position diawhich is adapted to engagean integral eye H, which projects at right angles from a lug E on thecollar E, thus forming a hinged A second lug E projects from the collarEdiamet rically opposite said lug E and carries a pin ,N, upon which theforked end of the lever B.

is mounted. Said lever R carries a springactuated dog T, which ismounted in a central chambered portion of the handle, as shown clearlyin the drawings, and is held in the space intermediate the forked endsof the lever by means of the spring S, the ends of which spring bearbetween the end walls of a recess Q in the lever. A portion of thecircumference of said dog is threaded, as at J,

and an adjusting-nut L is mounted upon said threaded circumference andadapted to regulate the tension of said spring and the throw of the dog.The crotch of the lever intermediate said arms is inclined, as at W,against which inclined surface the cam edge of said tongue is adapted tocontact as the lever is thrown down against the coupling-head,whichmovement will have a tendency to force the ends of the couplers withconsiderable pressure against thewasher interposed between thecoupler-heads, thereby producing a tight joint.

In applying the device the collars D and E are applied to thecoupler-heads before the latter are put together, and as thecouplerheads are brought together the hook on one of said collars iscaught in the eye upon the other one and the lever pushed down upon saidtongue, and after the two heads have been tightly forced together andthe end of the dog comes in contact with the notch in said cam edge thespring will throw the dog into the notch and the coupler-heads will besecurely locked together.

While I have shown a particular construction of apparatus embodying mycoupler device, it will be understood that I may make alterations in thedetailed construction of the .same, if desired, without departing fromthe spirit of the invention.

Having thus fully described my invention, what I claim as new, anddesire to secure by Letters Patent, is-

the lever is thrown toward the coupling, a spring-pressed bolt mountedin said handle, with its inner end beveled and adapted to engage a notchin said catch, an adjusting-nut mounted on the outer threaded end ofsaid bolt, adapted to regulate the throw of the latter, as set forth.

In testimony whereof I hereunto aflix my signature in presence of twowitnesses.
